Design of Multi Moving Target Detection and Recognition System Based on Edge Information Fusion
Motion target detection algorithms are easily affected by noise and changes in brightness,leading to the presence of false targets,making it difficult to meet the requirements of accuracy and real-time performance in practical applications.To address these issues,this paper proposes a real-time multi-object motion detection algorithm that incorporates edge information and constructs a video image processing system on FPGA platform.Firstly,the algorithm utilizes a Gaussian filtering enhancement algorithm to im-prove noise resistance.Subsequently,the three-frame difference method is employed to reduce the probability of false targets.Simul-taneously,the edge detection is applied to the images,and the edge information is fused with the results of the frame difference meth-od.Finally,the multi-object recognition algorithm is used to identify and label the moving targets.The algorithm fully utilizes the parallel computation and pipeline operations of FPGA.Experimental tests demonstrate that the detection and recognition system can achieve the real-time detection of up to 16 moving targets in 1280×720@60 Hz video scenes.
